## Abstract

Total world wide trade in edible seaweeds is presently over Aus$l billion, mainly amongst Japan, Korea and China, of which Japan probably has the greatest proportion of trade. Trade is mainly in three varieties of seaweed:- Nori (Porphyra spp.), Kombu (kelps) and Wakame (Undaria spp.). The value of other unspecified seaweeds imported by Japan in 1986 from a variety of countries was Aus$3 million or 5% of the total value of Japan’s seaweed imports.
Tasmania has an abundance of seaweed species, many of which are similar to those utilized elsewhere. A hypothetical costing of mariculture of various seaweeds here in Tasmania demonstrates the potential to supply seaweeds at competitive prices to the edible market.
A selection of samples sent to Japanese trading companies resulted in limited interest. A lack of understanding of the requirements of the Japanese edible market cannot be discounted. Any future marketing requires the direction of somebody with expertise and an understanding of the market in this area.
Analyses of arsenic concentrations in Tasmanian seaweeds gave low values. This is consistent with Tasmania’s claim that its waters are comparatively free from pollution. Expansion of market interests in seaweeds for alginate and agar industries remains a possibility.
